Rumors in the press (CRN – Project Zephyr) have speculated that VMware is about to offer its own cloud has created an email thread among us analysts that we felt was worth sharing. The core issues discussed in the thread are 1) what is VMware going to do about the success of Amazon EC2, OpenStack and CloudStack, 2) what is the relationship between VMware’s success in the enterprise and potential success in a public cloud, and 3) what is the best way for companies to “on-ramp” into the public cloud. This lead to a discussion which started on the point of whether or not vSphere was scalable enough to be a platform for a successful public cloud computing offering.

Cloud based security is about securing the data, yet compliance requirements are often about securing the environment, such as PCI’s requirement for web application firewalls, which protect web servers and perhaps applications and imply protection of data. But they do not directly protect data. How can a Software Defined Data Center implement a form of Software Defined Security automatically to meet not only compliance requirements, but security around a particular mote of data? Continue reading Software Defined Security: Is it Achievable?
VMware purchased Nicira, backed the Openflow Community, and is now touting software defined data centers (SDDC). But what is a software defined datacenter? Is it just virtualization or cloud with a software defined network? Or is it something more than that? Given heavy automation and scripting of most clouds, do we not already have SDDC? If not where are we going with this concept? What does SDN add to the mix? Continue reading Is the Software Defined Data Center the Future?
While looking around the web for anything new with virtualization, I kept seeing more and more posts and articles about the new type of virtual hypervisor. Type 0, now this sounds interesting and I found these definitions for each type of hypervisor. Continue reading Type 0 Hypervisor – Fact or Fiction
Just what are storage hypervisors? There are several companies that claim to have storage hypervisors. Wikipedia states that a hypervisor is “conceptually one level higher than a supervisory program”. We also know that from our normal use of hypervisors that they manage the underlying resources that a guest uses. Do these definitions work for a storage hypervisor? Continue reading Storage Hypervisors: Worth the Hype
The 6/28 Virtualization Security Podcast we spoke about attacks, defense in depth, and compliance with Davi Ottenhiemer and Matt Wallace. Davi and Matt just published a book (available on the Virtualization Bookshelf under Security) on how to defend your virtual environment against attack. Unlike other books, this approaches the problem from the point of view of well know attacks. It even gives examples of some of the more interesting attacks against any of the virtual environments, not just VMware vSphere. The discussion eventually found its way to even newer attacks and their impact on the environment. Continue reading Defense in Depth: Know Your Attack Surfaces
